摘要: 采用缓慢蒸发溶剂法在水中合成了2个含双磺酸基的化合物A-2,5-DSA·(Hphen)2·2H2O(1)和[Co(phen)2(H2O)2]·(A-2,5-DSA)·3H2O(2)(A-2,5-DSA=苯胺-2,5-二磺酸根离子,phen=1,10-邻菲罗啉)。化合物1中,相邻的质子化的1,10-邻菲罗啉反向堆叠在一起,水分子通过氢键与(Hphen)+和苯胺-2,5-二磺酸根离子相连,形成二维的层状结构。化合物2中,钴离子与2个1,10-邻菲罗啉和2个水分子配位,构成[Co(phen)2(H2O)2]2+阳离子。3个自由的水分子通过氢键将苯胺-2,5-二磺酸根离子和[Co(phen)2(H2O)2]2+连接形成三维网状结构。两个化合物中苯胺-2,5-二磺酸根离子均起到平衡电荷的作用。室温下2个化合物均具有荧光性质,其最大发射峰分别在601 nm和441 nm。 |

Abstract: The two compounds containing disulfonate groups A-2,5-DSA·(Hphen)2·2H2O (1) and[Co(phen)2(H2O)2]·(A-2,5-DSA)·3H2O (2) (A-2,5-DSA=aniline-2,5-disulfonate anion, phen=1,10-phenanthroline) were synthesized by the slow solvent evaporation method in water. In the compound 1, the adjacent protonated 1,10-phenanthroline cation (Hphen)+ reversely stack together. The water molecules connect to the (Hphen)+ cations and aniline-2,5-disulfonate anions to form two-dimensional layered structure through the hydrogen bonds. In the compound 2, the cobalt ion coordinates with two 1,10-phenanthroline and two water molecules to generate the[Co(phen)2(H2O)2]2+ cation. The three free water molecules connect to the[Co(phen)2(H2O)2]2+ cations and aniline-2,5-disulfonate anions to form three-dimensional network structure through the hydrogen bonds. In the two compounds, the aniline-2,5-disulfonate anions only balance the charges. The compounds exhibit the luminescence properties with emission maximum at 601 nm and 441 nm at room temperature, respectively. CCDC: 978180, 1; 978179, 2. |
